Practice Exam 1: MAP 4305 * 1. Does xy ′′ + ( x + 2) y - y = 0 , x > 0 , have a solution which is bounded near zero? Notice that to answer this question, you only need to consider the indicial equation. 2. Determine the form of a series expansion about x = 0 of 2 linearly independent solutions to: x 2 y ′′ - xy + (1 - x 2 ) y = 0 , x > 0 . Do not find a recursion formula for the coefficients. 3. Let J ν ( x ) be the Bessel function of the first kind of order ν 0: J ν ( x ) = summationdisplay n =0 ( - 1) n n !Γ(1 + ν + n ) parenleftBig x

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
